Band-tailed Antshrike Thamnophilus melanothorax

A rarely encountered large antshrike. Both sexes are distinctive; male is mostly black with a broad white tail band, whereas female is mostly rusty-colored with a black face and throat. Pairs inhabit disturbed areas in forested regions and are especially fond of dense vine tangles. May ascend into midstory but usually remains in undergrowth where they are difficult to see. Song is a slow series of hollow notes, much slower than other antshrikes in range; also harsh churring in alarm. Range incompletely known.
